Police busted Ho Chi Minh City's largest pirated compact disc ring in a series of four raids Tuesday.
District 7 investigators found disc recorders, label makers and thousands of DVDs and VCDs containing illegal content at two houses owned by Le Thanh Vu, 41.
Police had previously observed trucks driving discs from a warehouse in District 4 to Vu's houses during a one-month investigation.
Thousands of more discs containing copyright violations were found in a raid of the warehouse.
The storage facility was being used by Toan Cau (Globe) Commerce and Service General Joint Stock Co., which was licensed to produce blank discs. But investigators said Toan Cau had been pirating TV, music and films instead.
Nguyen Ba Tung, a 53-year-old city resident, had registered the company in 2006.
Police found many empty discs imported from China and a modern disc production line worth billions of dongs at the warehouse.
They also found a large amount of pirated music and movies on DVDs and VCDs at a house belonging to Nguyen Quoc Vinh, 36, in Tan Binh District.
Investigators said the discs were packaged at Vinh's house before being distributed around the country.
More than 300,000 pirated discs were seized in the raids. Police said they were investigating the roles of people involved in the ring, which accounts for 60 percent of the pirated disc market in HCMC.
A source from the city police said Toan Cau Company had been working 24 hours a day in the run up to the soaring demand expected during the Tet (Lunar New Year) holiday next month.
